MAX5903 MAXIM [Maxim Integrated Products], MAX5903 Datasheet - Page 10

• Manufacturer Part Number: MAX5903
• Description: +72V SOT23 Simple Swapper Hot-Swap Controllers
• Manufacturer: MAXIM [Maxim Integrated Products]

Good thermal contact between the MAX5902/
MAX5903 and the external MOSFET is essential for the
thermal shutdown feature to operate effectively. Place
the MAX5902/MAX5903 as close as possible to the
drain of the external MOSFET, and use wide circuit
board traces for good heat transfer. See Figure 7 for an
example of a PC board layout.
